"Nikkei.com on Monday reported that an online Sony gaming network has once again fallen victim to a cyberattack. This time, the attack may have exposed the credit card numbers of thousands of Sony customers from around the world. According to the report, over 12,700 customer credit card numbers were stolen during a breach of Sony’s online gaming network, Sony Online Entertainment. According to Nikkei.com, Sony discovered the possible attack on Sunday."

"Visa is not a debit card. Visa is a credit card. You can't use bank cards in The Netherlands without the PIN number. It's how the system works."

I'm no expert on the matter, but as far as I know in the US, Visa/MC actually do handle the processing for all the debit cards.

My debit card has a Visa logo.

I don't actually use it, legally speaking I have no rights against Visa or my bank if they permit fraudulent purchases against my debit card. With credit cards, US law places the burden of proof on them.

It may be different in other countries that don't embrace monopolies like the US.
